Title: Corn havester
Inventor: RANEY RUSSELL RAYMOND
IPC: A01D45/02
Filed: 1960-04-19
Abstract: 885,936. Corn harvesters. AVCO CORPORATION. April 19, 1960, No. 13617/60. Class 6(3). A tractor-drawn corn harvester comprises sheet metal crop dividers 12, 14 and endless chains 16, 18 moving the corn stalks into the gap 50 between two, rearwardly inclined, rotating, ear-snapping rollers 20, 22. The roller 20 comprises two parts 20a and 20b jointed together at 40 and supported in adjustable bearings 78, 80, the relative positions of the two parts being adjusted so that the front part 20b diverges from the roller 22 to define the gap 50, and the rear part 20a extends parallel to and above the roller 22 to snap the ears from the corn stalks. The ears fall on to a conveyer 28 extending beside the rollers, the floor of the conveyer being formed with an extension 36 passing beneath the roller 22 to prevent crop wastage. The rear part of the roller 20 and the complete roller 22 are positively driven from the power take-off of the tractor drawing the harvester. The joint 40 between the two parts of the roller 20 may take the form of a universal joint, in which case the forward part 20b of the roller is also positively driven, but alternatively the joint may be of the ball and socket type, in which case the part 20b is merely driven by friction occurring at the joint. In this latter case, drive to the front part of the roller is interrupted in the event of ears of bent corn stalks entering the gap 50, thereby preventing premature severance of the ears from the stalks.

Title: Improvements in and relating to sighting devices for guns
IPC: F41G5/16
Filed: 1928-05-10
Abstract: 306,764. Brewer, G., (Krupp Akt.-Ges., F.). May 10, 1928. Sights and methods of sighting.- Relates to sights F<1> mounted on a rocking platform A, such as a ship, by means of a member B trainaible on a vertical pivot b' relatively to a fixed base A', and a second member C adjustable in elevation relatively to the first member B. These members B, C have previously been adjusted by hand while the ship rolls. According to the invention, a gyroscopic device K is provided to maintain the members Band C substantially stable in space automatically, thereby relieving the sighting officer of a considerable amount of work. The gyroscope casing K is trunnioned in a gimbal ring N, which is itself trunnioned in a bracket M which is trainable about a pivot m<1> on a base A<2>. The bracket M is given the same training as the member B of the sight mounting by direct mechanical coupling or by means of motors M<2>, E rotating simultaneously and alike. The trunnions n<1>, k of the gyroscope mounting carry induction coils N', K<2> of magneto motors, the currents from which are therefore proportional to the rocking speed in the corresponding vertical planes. These currents are amplified by devices P, P<1>, such as amplifying valves, and then control generators D<2>, E<2> driven by a motor Q on the Leonard principle; and these generators D<2>, E<2> operate the motors E, D, which elevate and train the members C, B of the eight mounting and maintain these members substantially stable in space. Resistances are provided to adjust the action of the current from the amplifiers P, P<1> on the generators D<2>, E<2>. Separate devices for hand control of these generators may also be provided to enable the sighting officer to adjust the settings of the members B, C; or a hand control of these members may be superimposed over the control by the motors E, D, for example as shown in Fig. 3, by means of a differential gear U controlled independently by the motor E and a handle u<1>. In the latter case the motor M<2> of the gyroscopic device is not synchronized with the motor E but with a separate motor W geared directly to the member B, the motor W serving also to control the training of the distant gun. The member C aforesaid carries, as heretofore, a cardan ring G to which is in turn trunnioned a gyroscope casing F carrying the sight F<1> and maintaining this sight hori. zontal. A pointer H is set is elevation by a motor f<3> and registers with a member g<1> on the cardan ring G.

Title: Method of locating members or structures
Inventor: HAYNES GEORGE LESLIE
IPC: F16B21/20
Filed: 1964-04-03
Abstract: 1,093,373. Stud and socket fasteners. JOSEPH LUCAS (INDUSTRIES) Ltd. March 31, 1965 [April 3, 1964], No. 13802/64. Heading E2B. A method of locating two members of structures against relative separation comprises the steps of forming a hole 14 in a first one of said members or structures, forming or providing an annular groove 14 opening into the hole, fitting a resilient ring 15 into the groove so that it extends radially inwardly of the hole, forming a hole 16 in the second one 10 of said members or structures, passing an elongated cylindrical member 17 through the hole 16 in the second of the two members or structures and into the hole 14 in the first member or structure, the arrangement being such that the members or structures are located against relative separation by retention of the elongated member by the frictional engagement of the resilient ring with the elongated member. As shown, the first member or structure consists of a plate-like part 11 and a body 12 and the resilient ring 15 is fitted into the groove 16 before the plate-like part 11 is applied to the body 12. The thickness of the ring 15 is such that when the part 11 is applied to the body 12 the ring is subject to axial compression. The member 17 may extend beyond the hole 16 in the member 10 or, alternatively, it can terminate flush with the upper surface of the member 10.

Title: Improvements in a method for central heating by steam and means for carrying out this method
IPC: G05D23/275
Filed: 1930-05-05
Abstract: 353,550. Heating buildings ; electric switches. MOREAU, H., 14, Rue ThÚodore de Banville, Paris. May 5, 1930, No. 13808. [Class 64 (ii).] Steam is admitted to the radiators of a central heating system at predetermined short intervals, which may be varied by thermostatic or windactuated devices, the steam admission means being operated electrically through circuits controlled by rotatable clock-driven means. One form of control comprises a clock-driven drum 1, Fig. 1, having insulating cam segments 6 on its conducting surface, and a spring contact arm 9 secured to a fixed post 10. The duration of the contacts may be varied by axial displacement of the drum, which may be effected by a hand-wheel 8 of a screw and nut mechanism, or from an anemometer or other wind-sensitive device. Another form of control comprises an insulated clock-driven drum 1, Fig. 2, with grooved conducting segments 6 engageable by a pivoted contact arm 9, the end of the arm being held in any one groove while making contact. When off the segments the arm is free to be moved to a position determined by a thermal element 13. A number of radiators in various rooms, or groups of radiators, may be controlled centrally by electric circuits, in such a manner that if all the rooms are below a desired temperature the clock control is over-ridden and steam is supplied, whereas if one or a few rooms only are cold, the clock control remains operative.

Title: Improvements relating to dynamometers
Inventor: TROIELLI GIOVANNI
IPC: G01L3/20
Filed: 1956-05-04
Abstract: 784,676. Air-brake dynamometers. SOC. PER AZIONI ASPERA. May 4, 1956, No. 13846/56. Class 106 (2). A dynamometer for measuring engine power output comprises a multi-stage axial flow air compressor operating in a closed cycle. The input shaft 6, Fig. 2, is connected through interchangeable gears in a housing 40b with a shaft 11 coupled to and driving a drum 49. The drum 49 carries a plurality of blades subdivided into four sets 13a, 13b, 13c, 13d, each blade being mounted on a spindle rotatable in the drum 49. The blades of sets 13a, 13b give an axial air flow opposite to the air flow set up by the blades of sets 13c, 13d. If the shaft 6 is rotated in a direction causing the air flows set up to collect in a central annular chamber 50, this air thus flows in the direction denoted by arrow a to a foundation 41, then outwardly in opposite directions, and finally upwards as denoted by arrows b back to the suction side of the blades. The angular setting of the blades 13a, 13b, 13c, 13d can be varied simultaneously by means of a handle (not shown in Fig. 1) that can be turned to cause a common axial displacement of a number of radial arms 15a, 15b, 15c and 15d rotating with the drum 49. These arms are coupled through pin-and-socket means with spindles 12a, 12b, 12c, 12d extending from the blades 13a, 13b, 13c, 13d and axial movement of said arms turns the spindles 12a, 12b carrying the blades 13a, 13b in one direction and the spindles 12c, 12d carrying the blades 13c and 13d in the opposite direction. The braking torque set up can thus be varied. Flow deflectors 27b, Fig. 6, are interposed between each pair of blade sets such as 13c, 13d and comprise flat discs in which slots are provided to deflect the flow from a set of blades, for instance the blades 13d, to oppose the rotation of the other set of blades, such as 13c. Measuring the torque. A rocking frame or cradle associated with the gears in the housing 40b has an arm 9, Fig. 7, acting on a piston 31 in a cylinder 32 filled with liquid at one end 35. When the cradle tends to rock, the resulting torque causes the liquid in the cylinder to be compressed and actuate a pressure gauge. Between the piston 31 and the cylinder 32 are a number of coaxial sleeves 65, 66 and one or more of these sleeves can, by means of a handle 33a and arm 67, be caused to rise with the piston 31 to vary the measuring range. Torque measurements can be made on engines rotating in either direction. For rotation in one direction the arm 9 tends to rise and causes the piston 31 and any sleeve coupled therewith to rise, the reaction being taken up by the plate 61. For rotation in the other direction, the spherical portion 9c of the arm 9 abuts the bottom 32c of the cylinder 32 which is thereby lowered by virtue of a slip coupling between the cylindrical boss 63a and a hole in the plate 61. Reaction is then taken up by a bracket 2 fast with the brake shell, abutted by the piston 31 through the arm 33 for the handle 33a.

Title: Improved Process of Hydrogenating Benzene
Inventor: LUMBROSO DANIEL
IPC: C07C5/10
Filed: 1968-03-22
Abstract: 1,171,564. Hydrogenating benzene. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 22 March, 1968 [24 March, 1967; 25 April, 1967], No. 13997/68. Heading C5E. In a process for hydrogenating benzene to cyclohexane in the liquid phase by means of a molecular hydrogen-containing gas in the presence of a suspension of solid hydrogenation catalyst (e.g. Raney nickel), a comparatively low amount of catalyst is used during the starting period of operation, and thereafter complementary amounts of catalyst are introduced until the density of the catalyst in the liquid phase attains a maximum desired value, and then catalyst injection is continued either continuously or stepwise whilst withdrawing either continuously or stepwise an amount of catalyst substantially equal to that introduced. The catalyst additions are conveniently made when the benzene content of the cyclohexane product becomes too high. Conditions may be adjusted for either complete or partial hydrogenation (95-99%), and in the latter case a further hydrogenation stage using a fixed-bed catalyst may follow. The hydrogen-containing gas may be first contacted with liquid cyclohexane, or with a hydrocarbon cut having more than 10 carbon atoms followed by liquid cyclohexane.
